I used to use plastic sticky tape (any colour) to insulate between inner and outer of RG-213 coax cable where I'd joined it (typical amateur using odd lengths!) . Then I found I was losing 1-2 dB at each joint at 70 cms so abandoned it and used foamed polyethylene instead which is fine. Don't know if there are different types of plastic tape with different RF properties. Walter G3JKV.
